<p>Is there any way to only bisect stable versions with <code>cargo bisect-rustc</code>? I'm trying to bisect an old bug and it'll take forever if it goes through each and every nightly <span aria-label="laughing" class="emoji emoji-1f606" role="img" title="laughing">:laughing:</span></p>

<p>Never mind, I figured out something good enough. I found the release dates and then entered those as start and end.</p>

<p>how, does bisect-rustc build the commit locally ? I remember that nightly builds are only stored 160 days.</p>

<p>also release dates minus 12 weeks more or less when nightly becomes stable.</p>

<p>Commit builds are 144 days I think, though we might've bumped it. Nightlies are stored indefinitely</p>

<p>I ended up being able to bisect to nightly-2017-03-04, but when I looked through the commit log nothing jumped out at me as being related.</p>
